Project Overview - Ningxia Jiangping Biotechnology Co., Ltd. was established on October 14, 2025, with a registered capital of 150 million yuan. The company focuses on bio-based materials, bio-chemicals, agricultural biotechnology, and environmental technology [3]. - The specific product types for the new project are not detailed, but the focus is on the bio-based dicarboxylic acid sector, which has seen increased activity with several companies launching new projects [3]. Understanding Bio-based Dicarboxylic Acids - Bio-based dicarboxylic acids are organic compounds produced through fermentation or biomass conversion, characterized by having carboxyl groups (-COOH) at both ends of their molecular structure. They are used in various applications, including polyesters, polyamides (nylon), biodegradable plastics, lubricants, fragrances, and hot melt adhesives [4]. - They can be categorized into two main types: aliphatic dicarboxylic acids and aromatic dicarboxylic acids. Aliphatic dicarboxylic acids are further divided based on the number of carbon atoms: short-chain (C2-C4), medium-chain (C5-C9), and long-chain (≥C10) [4]. Aliphatic Dicarboxylic Acids - Short-chain dicarboxylic acids like malonic acid (C3) and succinic acid (C4) have achieved commercialization, with bio-based succinic acid being the most advanced in terms of industrialization [5][6]. - Medium-chain dicarboxylic acids such as hexanedioic acid (C6) and nonanedioic acid (C9) are also commercialized, with major producers like Cargill and Emery Oleochemicals [6]. - Long-chain dicarboxylic acids, including decanedioic acid (DC10) and dodecanedioic acid (DC12), have been industrialized, with companies like Kasei Biotech leading the market [8]. Aromatic Dicarboxylic Acids - Common bio-based aromatic dicarboxylic acids include 2,5-furandicarboxylic acid (FDCA) and terephthalic acid (PTA). China has established a strong presence in the FDCA sector, with over 10 companies involved in the industry [9]. - Internationally, Avantium is a pioneer in the FDCA field, having built a 5,000-ton commercial production line [9]. - The bio-based PTA production route involves converting bio-based naphtha to bio-based para-xylene (PX) and then to PTA, with companies like Hanwha and Taiwan Oriental Petrochemical participating in this market [9]. Industry Developments - Companies such as Jinfa Technology and Huaheng Biotechnology have launched projects to increase their production capacities of bio-based dicarboxylic acids, with Jinfa's capacity expected to reach 150,000 tons per year by December 2025 [10]. - The article also mentions the upcoming Bio-based 2026 conference, which will focus on the latest developments in bio-based chemicals and materials, providing a platform for industry collaboration [12][13].
